ERICSSON BULLETIN'S


The Ericsson Bulletin was a, magazine style, company publication which described the companies apparatus in an easily understandable manner, but also in a way that advertised the products as well.  The Bulletin started in July 1932 and continued until January 1966, when the Ericsson (Etelco) Bulletin and the A.T.E. Journal were merged to form a single quarterly publication called the Plessey Communications Journal (Ericsson had been taken over by Plessey in 1961).

Below is the Bulletin index from July 1965 (B.6507/1).  Articles that are linked, have been produced from the actual bulletins.  Only customer apparatus specific articles have been reproduced.
